Hydraulic Pump PTO Speed Increase Gearbox for Tractors, Power rated to 20kW (27 HP input ) 7100 series.
The 3:1 Ratio takes the 540 RPM tractor output and converts it to 1,620 RPM which is an ideal rotation speed for Hydraulic Gear pumps.

With the correctly sized pump mounted to the gearbox: the following oil flows and pressures can be generated.

• 80 Lt/min at 1,800 psi (125 bar)
• 70 Lt/min at 2,200 psi (150 bar)
• 60 Lt/min at 2,500 psi (175 bar)
• 50 Lt/min at 3,000 psi (200 bar)
• 40 Lt/min at 3,600 psi (250 bar)

If you require a hydraulic attachment to run off your tractor but don't have enough hydraulic flow available, this may be the answer.

Match up a pump with the correct flow rate, add an oil reservoir & you have a hydraulic power source.
In the image below is a power/flow chart to help choose a gear pump. This gearbox is rated for a maximum of 20 kW hydraulic power internal stress will cause the gearbox to fail prematurely.

The gearboxes are used mainly for connecting hydraulic pumps to the power take-offs of agricultural tractors ( Male 6T 1 3/8” shafts).

PTO output, standardised at either 540 or 1,000 rpm, is, in this way, increased to optimum operating speeds for the hydraulic pumps.
At 540 Rpm, the output speed is 1620 RPM

Used to power hydraulic Auger, front-end loaders, mowers, rotary sweepers, post hole hammers and borers, pile drivers etc.

There is a choice of three configurations below. Also a choice of 'Spline' coupler.
These gearboxes only take Group 2 or Group 3 DIN and SAE 2 A and SAE B mount pumps.

Please see the chart, & then our pump listings.

This 7000 series will only produce a maximum of 60 LPM @ 175 Bar / 2600 psi.
For more flow with higher pressure, please see our larger 50HP gearbox.

This step-up gearbox has a ratio of 3:1 with a Group 3 Din Mount 1:8 tapered shaft gear pump.
at 540rpm the gearbox will produce 1620 rpm, giving a flow rate of litres per min; these are examples (other incremental pump sizes available,) Please note; This gearbox is rated for a maximum of 20 kW hydraulic power. If you oversize the pump, & run at a higher pressure than is stated in the chart below, internal stress will cause the gearbox to fail prematurely. No warranty if large cc pumps are run at pressures over what is in the chart below.

Specifications — 700 Series

Male, female, or female with lock?

Male takes a female driveshaft yoke. Female slips over a male tractor stub. Female with lock adds a push-collar quick release so the shaft comes off by hand — worth it on an implement that comes on and off regularly.

Female / female through-shaft (KM7106-4E) takes a drive at both ends, so you can run the gearbox mid-line and still pass drive through to another implement.

The coupling is a separate part

Gearboxes do not include the pump coupling. Timalco supply them separately and it is the single most commonly missed item on a PTO order — the box arrives and the pump will not mount.

Oil: SAE 90 gear oil or Universal Tractor Transmission Oil. Rotation: clockwise viewed from the input shaft — running one backwards will destroy it.

Updated 4/8/2026 — full Timalco variant range added (SAE A and SAE B mounts), coupling guidance and specifications from the 2025 catalogue.
